Topic: 3 phase motor megger testing (Read 847 times)

I have a 3 phase motor When testing with a megger do you only test from each winding to ground.When I do a ohm meter test of the 6 wires I get a reading wirer green 1&2. 9.7ohm White 3&4. 9.7 ohm Yellow 5&6 9.7 ohm readings .This is the order in witch they wer connected to the terminal block.When I connect any black wirer or white wirer in any order I get a ohm reading between 17 and 10 ohm black to black or white to white black to white.I do not under stand this layout.Are all the wind endings going inside.The windings do not go to earth.Grer
